Steel Unthreaded Pipe Fittings
- For Use On:
EPDM Rubber O-Ring: Ethylene Glycol, Propylene Glycol, Water
Buna-N Rubber O-Ring: Air, Lubricants, Propane, Fuel Oil, Natural Gas, Diesel Fuel - Specifications Met:
EPDM Rubber O-Ring: ASME B31,1, ASME B31.3, ASME B31.9, Uniform Plumbing Code, FM 1920, UL 213, Uniform Mechanical Code
Buna-N Rubber O-Ring: ASME B31.1, ASME B31.3, ASME B31.9, Uniform Plumbing Code, ANSI LC4/CSA 6.32, Uniform Mechanical Code, International Fuel Gas Code - Maximum Pressure:
EPDM Rubber O-Ring: 200 psi @ 72° F
Buna-N Rubber O-Ring: 125 psi @ 72° F - Pipe Nipples and Pipe: Use Schedule 40 Steel
- Flanges: Use Class 150 Steel
Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat. An internal gripping ring and rubber O-ring create a secure seal when crimped. They are designed to leak if fittings have not been crimped; a colored dot marks the leak path so it's easy to spot unsealed connections. These steel fittings are coated in zinc-nickel to resist corrosion, but will rust if frequently exposed to saltwater or harsh chemicals. They are comparable to Viega MegaPress steel fittings.
Fittings comply with the Uniform Plumbing Code for plumbing systems and the Uniform Mechanical Code for HVAC and refrigeration. They also meet ANSI/ASME B31 code requirements for use in pressure piping systems.
Buna-N rubber O-rings hold up to natural gas, propane, diesel fuel, lubricants, and other oils. Fittings with these O-rings are often used in fuel gas systems and air lines. They meet the ANSI LC4/CSA 6.32 standard for fuel gas systems and comply with the International Fuel Gas Code.
Connectors with center stop have a small internal ridge that prevents the pipe from sliding too far into the fitting. Insert the pipe on each side of the connection up to the center stop to ensure a tight seal.
Unions separate into three pieces. Unscrew and remove the center nut for quick access to a line.
Bolt two same-size flanges together with a gasket (sold separately) to create a removable connection to valves, pumps and other equipment.

Crimping tools seal fittings in less than five seconds. These tools are cordless, so you can take them to any job. Connect the jaw or ring that matches your pipe size to these tools, then pull the trigger to crimp the fitting. The pivoting head lets you access connections from any angle.

Jaw and ring sets include three jaws, three rings, and one ring actuator jaw. Jaws are for pipe sizes 1/2 to 1; they fit directly into the crimping tool. Rings are for pipe sizes 1 1/4 to 2; clip the ring around the fitting and use the ring actuator jaw and crimping tool to press the open ends together.

Fittings for Stainless Steel Tubing
- For Use With: Acetylene, Air, Butane, Compressed Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Helium, Hydraulic Fluid (Petroleum Base), Kerosene, Mineral Oil, Natural Gas, Nitrogen, Propane, Soap Solutions
- Temperature Range: -10° to 400° F
- Tubing: Use with seamless 316Ti or 321 stainless steel
- Specifications Met: DIN 3861
Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps. However, rubber sleeves can’t withstand temperatures as high as metal ones. To create the strong seal, tighten the included nut. These fittings are made of 316 stainless steel, so they have excellent corrosion resistance. They’re also known as flareless fittings. All meet DIN 3861, which is an international standard for compression tube fitting specifications.
BSPP and metric male threads have a gasket to prevent leaks.

Threaded Hose Fittings for Compressed Gas
Use these fittings to connect welding hose to pressure regulators and torches. They are also known as CGA (Compressed Gas Association) fittings. Fittings are brass for good corrosion resistance.
Fittings with left-hand threads are identified with a notch in the nut.
Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.

- Maximum Pressure: 200 psi @ 72° F
- Maximum Temperature: 120° F

Pipeline Fluid Blockers
Also known as paddle blinds, these fit between two flanges to temporarily block the flow while you work downstream.
304 stainless steel blinds are more corrosion resistant than steel blinds.
